Regarding: Professional installation of ducted air circulation and ducted condensation control systems 

Workmanship Guarantee

Home Efficiency Group undertakes to act in a professional manner, install your system with diligence, leave your home in a clean and tidy state, and fix any damage that may be accidentally caused in the course of installation.

Warranty

A 1 year manufacturer’s warranty applies to the inline duct fans that we professionally install. Home Efficiency Group undertakes to swap over the fans at our expense within a reasonable time period of notification of a manufacturing defect in the fan, unless caused by physical trauma post-install, a power-surge within the electrical system of the house (e.g. caused by lightning strikes) or other force majeure events.

Note: This style of high-volume air fan has been used extensively in New Zealand for 15 years. They have a very low failure/return rate, so you should reasonably expect long tenure from your investment.

Condensation Control

Home Efficiency Group undertakes that its condensation control systems will eradicate troublesome window condensation from your home within the ducted areas of the house. Troublesome window condensation is defined as beading and/or streaking condensation that pools up to cause damage, or condensation that is persistently present to allow the formation of mould or extensive dust mite colonies. Light condensation over a small percentage of the window is to be expected on particularly cool nights/mornings as there is always moisture in the air. Sometimes the effect of the system cannot penetrate behind enclosed, reasonably draught-proof window drapes or blinds, but the condensation is usually light and will dry off before it can cause any damage.

It should be understood by the customer that there is usually a trade-off between room warmth and window condensation. When dry air from the roof cavity is used to displace moist air from the liveable parts of the house, the house temperature may be subtly cooled when the roofspace air is cool e.g. at 3am during winter. This is usually a negligible temperature effect as the roofspace air is only a small proportion of the heater-warmed air that is being ducted throughout the house, but does depend on heater usuage and house usage (living habits). In general, though, the greater proportion of roofspace air used (i.e. for severe condensation), then the cooler the rooms (but the window condensation is completely gone). There is usually a happy balance between the warmth and window condensation in most cases, though.

E&OE

Home Efficiency Group reserves the right to vary, rescind or add to these warranty terms at any time.

Pricing Notes

Quotations are valid for 21 days from date of quotation. We will make every effort to avoid any additional costs, and will discuss any changes with you beforehand. Pricing includes the supply of the ducted air circulation system components, installation and electrician costs. Travel is itemised as extra, and is calculated on a shared travel cost basis of 2 or 3 jobs on the same day within relatively close proximity; we reserve the right to recover full travel costs if your job is the only one in the general area or the only one on that day if you require the installation prior to another job being available in your area. Home Efficiency Group reserves the right to refuse jobs due to construction factors (skillion roofs aren’t applicable, for instance), location factors (some remote locations are difficult to schedule in a timely manner) or for other reasons at our sole discretion. 

Specifically, Home Efficiency Group reserves the right to charge extra for:

1. Electrical work that takes more than 2 hours (usually 1 to 1.5 hours)
2. Alterations to the specifications by the customer, or significant oversight or error in the quotation;
3. Sudden and unexpected price variations from suppliers;
4. Additional travel that is required outside of a single direct travel to and from the job site;
5. Unforeseen circumstances that impinge on the timely installation of the service or costs relating to the service;
6. Unforeseen lath/plaster ceilings & double ceilings etc... which requires greater time to work with & clean-up; 

For pricing of non-standard configurations or installations, please contact our sales team on 1300 96 80 60.

Payment Terms

Payment of invoices must be made on the day of installation following successful testing of the system by the electrician or installation technicians. Payment can be made by Visa,  Mastercard, Cheque, Direct Deposit (e.g. online or phone bank transfer) or cash. The installation technicians will be able to provide a receipt. E&OE.

Privacy

We respect your privacy – customer details are never sold to 3rd parties. We may contact you from time to time with other home efficiency-related products or services.

Care of installation

All care will be taken with the installation of inlets and outlets in your dwelling. However, if your ceiling construction is “lath and plaster” (which can vary widely in its quality of workmanship) or of poor construction of other materials, then Home Services Group does not take responsibility for damage that occurs from work being undertaken in the normal installation process with requisite due care.

Expectations / Outcomes

As each house is individual in nature (workmanship, air volume, draughts, sub-floor ventilation, insulation, inherent moisture content & other issues) and each household has different patterns of lifestyle use (e.g number of showers taken, temperature of heaters, running times of heaters, etc...), Home Efficiency Group cannot warrant or be held responsible for the effectiveness of the system to distribute heat or alleviate issues (although we try very hard!).

Safety Measures

We proceed on the assumption that the Customer has, or will prior to use of the Home Efficiency Group system, implement adequate safety measures in the use of existing heaters, including, but not limited to, correct wiring, smoke detectors (in all bedrooms, living areas and passageways) and regular servicing of heaters/flues, etc...
